The most common symptoms were pneumonia (n = 10), chronic diarrhea (n = 6), infections plus dermatitis (n = 3), infections plus moniliasis (n = 3) or all of these (n = 3). The respiratory tract diseases were the most frequent infection type. Lymphadenopathy and hepatosplenomegaly were observed in 36% and 90% of RAGD patients, respectively. Auotoimmunity was recorded in three patients. CMV infection was detected in two patients with T + B + NK + phenotype.
